HAM E-FASTE N ER.

it open. Fig.3 is a top view of Fig. 2 and Fig. 4 a cross section online .20, 00, Fig. 1.

The letters a, b, represent the two hooks or loops of the hame fastener,each provided with a shank a, Z), of a reduced thickness, so that ashoulder or offset a b is formed at the junction between hook and shank.The rear end of each shank is bent inward at'right angles as at a 19?,to form a flange. The two shanks a, b, are pivoted to a joint link orplate 0, by the pivots a, b. These pivots are out of line horizontallyso that the fasteneris eccentric and held closed automatically. The link0, terminates at one end in a handle 0, having a grooved lower edge 0(Fig. 4) that engages the lower edge of the shank b, when the hook isclosed to aid in looking the fastener. To prevent spontaneous droppingof the handle, the shank b, may be slightly bulged as at where it entersthe grooved edge. The upper and lower edge of the link 0, is notched asat 0 and c, the notch 0 being adapted for the accommodation of theflange b and the notch 0 being adapted for the accommodation of theflange (1 when the hook is open (Fig. 2).

The operation of the device will be readily understood. To bring thefastener into engagement with the hames, the hooks are distended bypressing the handle 0, downward.

After the hooks are brought into engagement with the hames, the lever isswung into the opposite direction (arrow Fig. 2) in order to bring thehooks into their closed position (Fig. 1). In this position thelink c,is grasped between the two flanges (1 b and thus, even if the pivots a,1'), work loose in course of time, the pull on the books will alwayskeep the device perfectly rigid. While the hooks are closed, theshoulder b will receive the flange a and the shoulder a will receive theflange b so that the flanges are entirely concealed.

The advantages connected with this fastener are that it can be easilyopened and closed, has a wide reach, is very strong, simple and notliable to work loose.

What I claim is 1. The combination of link 0, having handle o, andnotches c 0 with a pair of hooks pivoted to such link and having flangesa b adapted to be received by said notches, substantially as specified.

2. The combination of link 0, having handle c, and notches c 0 with apair of hooks pivoted to suchlink andhaving the shoulders a b and theflanges a substantially as specified.

3. The combination of link 0 having grooved handle 0' with a pair ofhooks pivoted to such link and having flanges a adapted to engageopposite ends of the link, substantially as specified.

4. The combination of link 0, having a grooved handle a, and notches c 0with a pair of hooks pivoted to suchlink and having the shoulders o 19and the flanges a b substantially as specified.
